I hope it's true.

Is it just me, or does it seem like Marc is always touring non stop? lol I don't follow his c.d. releases and singles, but it seems like everytime there's a possible Jen sighting in writing, it's b/c Marc has a concert at whatever place. I'm like...again?

Anyway, I think there are Jen fans who'll embrace Marc's music, since he is very much an extension of her now, and b/c they also gravitate toward Spanish music to begin with. But there are probably those who would get a kick to see Jen perform live and are strictly a fan of her pop/r&b hits, with not much interest in listening to Latin music. I think for the most part though, their fanbases are pretty similar, especially for those people who like them as a couple.

They're also probably thinking, 'If we're gonna have to work, we might as well be together.' I honestly don't think they could be apart for more than a couple of days.
